InZOI ModKit Announcement

Hello, Creators.

At the end of May 2025, inZOI’s long-awaited ModKit will launch, along with our first modding update!

This announcement explains what will be possible with the ModKit and what modding features will be added over time. Please see below for details.

ModKit Release Preview

The inZOI ModKit is an official tool that makes modding easy and accessible for everyone. After the late May update, it will be available for download via the Epic Games Store. Major features include:

Download inZOI Assets

– In the late May update, representative meshes (FBX) and Json data files for outfit sets and standard furniture will be provided. Additional assets will be added through future updates.

– By editing the Json files used in-game, you’ll be able to freely adjust various states and conditions.

　- Example: A bed that restores sleep in 5 minutes

　- Example: Changing the Flirt buff duration to 10 hours

Maya & Blender Plugins

– Official plugins for Maya and Blender will be provided to make it easier to create inZOI 3D assets.

– These plugins let you import the downloaded meshes into your tools and use them in your workflow.

Create Unreal-Based Mod Projects

– Assets made in Maya, Blender, or other tools can be imported into ModKit and turned into Unreal plugin format mod projects.

CurseForge Integration

– Your completed mods can be uploaded and packaged on CurseForge.

– Other creators will be able to easily search for and download your mods via the in-game CurseForge interface.

InZOI Modding Roadmap Update

To help expand the inZOI modding ecosystem step by step, we’ve planned three modding updates throughout 2025. These updates will lay the foundation by expanding key features. Going forward, we’ll continue to evolve based on your feedback.

May Update

The May update will introduce modding tools for outfit sets and furniture, along with a data editing UI that makes it easier to modify game data. With the official launch of the ModKit, we’ll continue improving based on your feedback.

September Update

In September, modding will expand to character features like faces and hair, as well as architectural elements like doors, fences, pillars, and windows. You’ll also be able to create interaction-based content like conversations, voice, rewards, and motion.

December Update

In December, most outfits will become moddable. You’ll also be able to edit interaction scripts and access localization tools, empowering you to create deeper and more diverse content.

Additional Notes

Our modding policy will be published on the official inZOI website in mid-May 2025. It will include guidelines, restrictions, IP ownership, and monetization terms. Please refer to this policy when using modding features.

We’ll also continue gathering your feedback and working with you to build a better modding environment. To kick things off, we’ll hold a ModKit-themed AMA and launch a dedicated feedback channel. More details will be shared in a separate notice later in May.

We appreciate your interest in modding with inZOI!

Thank you,

The inZOI Team

Kjun’s Letter: Features and Plans in Development

Hello, Creators.

Kjun here.

In this letter, I’ll be sharing our plans for features currently in development, as well as the direction we want to take inZOI in the future.

Our team has spent the past month carefully reviewing and addressing frequently reported issues, including build stability, awkward emotional expressions, and a lack of depth in the Karma system. This experience has helped us once again realize how important convincing emotions and behavior is for a life simulation game. Thankfully, some players have responded positively to these fixes by expressing that emotions and conversations now feel more natural, which we truly appreciate. That said, there’s still plenty of room for improvement, so we remain committed to making inZOI a better experience for players.

In addition to our ongoing hotfixes, we’re actively working on the May and August updates. The May update will introduce long-awaited modding features to the game. While these features won’t support creating entirely new systems from scratch at launch, they will allow you to modify key in-game data and settings. We’re also preparing official plug-ins for Blender and Maya to make creating custom outfits and furniture easier, as well as features that allow players to work with various asset types such as textures, meshes, FX, and MetaSounds. Guidelines for creating assets will be shared via tutorial videos and the modding UI. We plan on continuing to expand modding support and aim to have all core features in place by December.

With a third city coming to the game, we’re also exploring new challenges. We’ve recognized the community’s desire for more gameplay depth and we will work towards offering content with the potential for richer storytelling and more engaging experiences. To match the vibe of the new city, we will be introducing smaller vehicles, such as motorcycles, along with highly requested vehicle personalization features. Since these will build upon our existing vehicle systems, some animations may seem slightly awkward at first. However, we believe that this will allow players to experience the thrill of weaving through the city on a smaller ride, enhancing both the storytelling and atmosphere aspects. We will continue to put our best effort into developing something that feels truly worthwhile.

While we made some adjustments to the Karma system in the previous hotfix, we will continue to refine and expand on it. To address the lack of meaningful consequences, we’re currently planning new crime-related content that allows Zois to be caught and go to jail, spawning additional events as a result. Our goal is to create deeper gameplay experiences where Karma-based interactions lead to logical, connected outcomes. If you have any fun or creative ideas, let us know in the #inzoi-feedback channel on our Discord!

Finally, we’ve noticed growing interest and discussion within our community surrounding inZOI’s use of AI. We will be addressing this topic in a separate announcement, and will continue to prioritize transparency and trust to allow players to continue enjoying inZOI.

While inZOI is far from perfect, we are working day and night to make it a true life simulation game through imagination, consideration, and experimentation. Every piece of feedback from each of our players helps point us in the right direction. We will continue listening closely to our community, so please don’t hesitate to share your thoughts with us.

Last but not least, I’d like to express my heartfelt appreciation for your continued support.

Thank you.

– Kjun
